Embodiment Construction

[0014] A production process for a high-strength strut aluminum alloy profile, comprising the following steps:

[0015] (1) Put the charge into the melting furnace for heating and melting. After the charge is melted, sprinkle 2 / 3 of the covering agent to cover it. When the temperature of the alloy melt reaches 705°C, use 0.3% MgF and 0.4% Refining CaF, put it into the furnace and let it stand for 10 minutes. When it reaches 745°C, press the block modifier into the bottom of the center of the furnace for modification treatment. After the modification reaction for 2 minutes, sprinkle the remaining 1 / 3 of the covering agent and let it stand for 10 minutes. It can be casted. Before casting, ensure that the mass percentage of each alloy element in the melt is: Si0.2-0.25%, Mg2.4-2.9%, Zn0.18-0.22%, Fe0.04-0.06%, Mn0 .03-0.05%, Sr0.04-0.08%, Th0.05-0.1%, Be0.02-0.03%, Cr0.15-0.25%, Zr0.05-0.08%, Ti0.02-0.04%, B0. 0015-0.0.002%, RE0.06-0.09%, the balance is Al;

Abstract

The invention discloses a production technique of a high-strength stay bar aluminum alloy section. The alloy comprises the following elements in percentage by mass: 0.2-0.25% of Si, 2.4-2.9% of Mg, 0.18-0.22% of Zn, 0.04-0.06% of Fe, 0.03-0.05% of Mn, 0.04-0.08% of Sr, 0.05-0.1% of Th, 0.02-0.03% of Be, 0.15-0.25% of Cr, 0.05-0.08% of Zr, 0.02-0.04% of Ti, 0.0015-0.0.002% of B, 0.06-0.09% of RE and the balance of Al. The three RE elements Sc, Gd and Ce are added into the modifier to obviously improve the metallurgical structure of the aluminum alloy, refine the crystal grain and reduce the crack sources of the aluminum alloy, thereby enhancing the strength and toughness of the aluminum alloy, and improving the working properties of the aluminum alloy. The aluminum alloy section has the advantages of high strength, light weight, favorable resilience and various excellent indexes, and therefore, is suitable for stay bars of various tents.

Description

technical field [0001] The invention relates to a production process of a high-strength strut aluminum alloy profile, belonging to the technical field of aluminum alloy materials. Background technique [0002] The poles of the tent are the skeleton of the tent. The quality of the skeleton material not only affects the life of the tent, but also affects the stability of the tent. The strength and firmness of existing struts made of aluminum alloy materials are not ideal, which cannot meet the actual requirements, and the resilience is poor. Therefore, it is urgent to develop a high-strength and high-performance strut aluminum alloy profile. Contents of the invention [0003] The object of the present invention is to provide a production process of high-strength aluminum alloy profiles for aluminum alloy struts, aiming at the shortcomings of existing aluminum alloy struts such as low strength and poor resilience. [0004] The technical scheme that the present invention adop...
